SPECIFICATION forming part of Letters Patent No. 563,471, dated July 7, 1896. Application filed May- 13, 1895. Serial No. 549,061. (No model.)

To all whom it may concern:

Be it known that ,we, ZACHARY T. and WILLIAM C. MEYER, of Suffolk, and State of Massachusetts, have of Boston, county invented an Improvement-in Sole-Sewing Machines, of which the following description, in

connection with the accompanying drawings, 1s a specification, like,letters on-the drawings representing like parts.

In some classes of boots and shoes the sole projects beyond the upper a greater distance around the fore part. than along the shank portions, such boots and shoes being 'frequently referred to as having a Scotch edge, and in other classes of boots and shoes the sole is made to project a greaterdistance beyond the upper along the outside ball portion than around the toe or inside ball portion, such peculiar shapebeing applicable to either a Scotch-edged sole or to a sole with'an ordinary edge, although at the present time it is usually seen in boots and shoes having Scotch edges.

In sewing the soles of such boots and shoes, and particularly in welted Work, it is desirable that the stitches connecting the sole and welt shall pass through said parts at a certain distance from the edge of the sole all around the forepart of the boot or shoe, regardless of the distance that the sole projects beyond the shank pprtions it is desirable that the stitches shall he farther from the edge of the sole. 1

This invention has for its object to improve the constructionof sole-sewing machines whereby this result may be carried out.

Our invention consists, essentially, in combmation, with stitch-forming mechanism, of two guides acting to externally guide the lasted boot or shoe, one acting along the shank and the other acting around the fore part,

the shank-guide holding the boot or shoe in such' relation to the stitch-forming mechanism that the stitches along the shank portions will lie at a certain distance from the edge of the sole, while. the fore-part guide holds the boot or shoe in such relation to the stitchforming mechanism that the stitches around.

the fore part will lie nearer to, but at a certain distance from, the edge of the sole, regardless of the distance said sole projects beyond the upper. f

In carrying out this invention, we find that good results. are

along the shank portions, and by employing as a forepart guide'one adapted to bear against the edge of the sole, although our invent-ion comprehends any other form or con,-

struction of independent shank and fore-part 6o guides when combined withstitch-l'orming mechanism. I

The shank-guide may beheld in I fixed relation to the stitch-forming mechanism, while the fore-part guide may be made movable with relation to the'awl and other members of the stitch-forming mechanism, and with a ma chine so constructed the boot or shoe is held with its'shank portion bearing against the shank or crease guide while sewing at, such point, and while sewing around the fore part the movable fore-part or sole-edge guide is brought into use and the boot .or shoe held against such guide. I

The crease-guide forthe shank portions and 7 5 the sole-edge guide of the fore part form a specific embodiment of our'invention, and

such specific forms are believed to possess many advantages. As a means of moving the fore-part guide in and out we have herein 8o represented a hand-lever, easily accessible to the operator, and intermediate parts connecting it with the guide. In either class of work above referred to itis also desirable to lengthen the stitches along the shank portion and shorten'themalong or around the fore part,andsoourinventioncomprehendsmeans for thus lengthening and shortening the stitches when connected with the means employed for operating the fore-part guide, '90

whereby the stitches may be lengthened along the-shank portion as they penetrate the sole farther from the edge, and shortened along or around the fore part as they penetrate the sole nearer to the edge.-

. Our invention is herein shown as applied to the sole-sewing machine such as represented in United States Patent No. 525,047, dated August 28, 189-1.

' Figurel shows in front elevation a'portion '100 of a sole-sewingmachine embodying this invention; Fig. 2, a plan View of the parts shown in Fig. 1; Fig. 3, a side view of the parts shown in Fig. 1; Fig. 4,.a detail to be produced" by employingas a. shank-guide one adapted to .enter the crease 55 referred to; Figs. 5 and 0, modifications to be referred to.

The awl a and its pivoted sector carrier a" sented in the patent above referred to, andas the stitch-forming mechanism itself forms no part of our present invention it is not deemed necessary to more fully illustrate it.

b represents a shank-guide, and, as shown in Figs. 1 to 3, is shaped to enter thecrease, although if differently shaped it would bear against the last. (See Fig. 5.) This shankguide b'is also made to serve as a work support or table. 1

0 represents a fore-part guide (shown in Figs. 1 to 3 as an upright arm) with an offset atits upper end, the abutting or acting face being shaped to bear against the edge of the sole, although it might be differently shaped to enter the crease. (See Fig. 6.)

The fore-part guide is made movable in and out with relation to the awl a and other members ofthe stitclnforming mechanism and therefore has a dovetailed recess at the lower end of its arm which receives a dovetailed portion (Z, formed .on a stationary plate 11,

which is secured to the framework. i

The lower end of the fore-part guide c,which is herein shown as a sole-edge guide, is connected by screws 2, or otherwise, with a plate 0', which is loosely connected by a screw 3, or otherwise, to one end of a lever c", pivoted at c to the plate d, the opposite end of said lever extending to the right, as shown, for a short distance. By swinging this lover a back and forth on its pivot c" the fore-part guide 0 is moved in and out, or toward and from the awl a and other members of the stitch-forming mechanism, (not shown,) or in and out with relation to the shank or crease guide I).

lvhen'sewing the boot or shoe, the shankguide I) enters the crease, and at such time supports'the boot or shoe, as, for instance, the welt may rest on such support, and the boot or shoe is thus guided along the shank portion. At the beginning of the fore part the fore-part guide 0 is brought into operative position, as, for instance, if said guide is adapted to serve as the sole-edge guide it will be brought forward against the sole edge and thus move the boot'or shoe out a short dis-' tance, so that the shank-guide no longer en tors or bottoms in the crease, although the welt still rests upon it, and the boot or shoe is thus guided by the sole-edge guide around the fore part. At the beginning of the opposite shank portion the fore-part guide 1; reccdes and the shank-guide is again brought into use. Thus the stitches will be formed along the shank portion at a certain distance fromthe edge of the sole, according to the relative distance between the acting face of the shank or crease guide and the'awl and other members of the stitch-forming mechanism, while along the fore part they will be formed in parallelism with the edge of the sole and at a certain distance therefromjxlepending upon the distance between the acting face of the fore-part guide and the awl. and other members of the stitch-forming mechanism or, if the fore-pa rt guide is formed to bear against .any other part of the lasted boot or shoe the stitches will lie at a certain distance from the edge of the sole, according as they are guided by such fore-part guide. To lengthen and shorten the stitches, as aforesaid, making. them longer in the shank and shorter around the fore part, we have supported the awl-carrier a upon an upright a, rising from a plate a, sliding laterally in ways provided for it in the frame, and a handlever e is pivoted at c to the frame, having a right-angular portion a", which engages a circuinferentially grooved head a of a stud screwed into the upright a so that by moving said hand=lever the awl-carrier is moved laterally. A The hand le'ver has a pin 5, (see dotted lines,) which enters the groove in plate 6 and is held frictiona-lly on a graduated plate 7, secured, to'the sli dingplate a. This feeding mechanism itself is not herein claimed. The handdever -e, by means of which the length of stitch is thus varied, is connected by a link 0 with the swinging lever c", which is used to operate the fore-part guide, and by means of thisconnection the parts are simultaneously operated, the stitches being lengthened when the handlevc'r e is moved toward the operator and the fore-part guide recedes,

and shortened when'the hand-lever is moved away from the operator and the fore-part guide brought into use.
